Just last month they had another important announcement for People -- their engagement. In a statement they wrote, "We are so thrilled to announce our engagement and can't wait to celebrate with our friends and family, including our second family at 'Once Upon a Time.'"

They started secretly dating in 2011 and finally made their romance known the following April. "It hit me like a blinding light," Dallas told E! of his love for Goodwin. "I thought, 'I'm in trouble now."

Goodwin is the star in the 2013 movie Killing Kennedy. Three years ago when engaged to Joey Kern, Goodwin spoke to InStyle UK about pregnancy, saying: "I want three or five children, but I need a bigger house or a smaller closet." Goodwin added "The only issue I have with aging is nothing to do with my career...it's that I want to have a lot of kids before I'm physically unable to do so."

Dallas has been married to English actress Laura Pulver from 2007 to 2011. He starred in Thor, but did not join the Thor 2 sequel to continue on ABC's Once Upon A Time.

Clearly the show is working for his personal and professional life. He also told E! "It's definitely a plus that we get to spend so much time together. I think it adds something; it adds a different dynamic to the characters that we're playing that we can bring to it."

Dallas calls Goodwin a "fantastic actress" who he learns so much from. She is his perfect match: "I look for fun and smarts - a witty, strong sexy woman."
